To all whom it may concern:

Be it known that I, JOSEPH A. Frnscrr- ING, a citizen of the United States of America, and resident of Utica, in the county of Oneida, in the State of New York, have invented new and useful Improvements in Winding and Dyeing Machines and Methods of Winding and Dyeing Yarn, Thread, and the like, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in winding and dyeing machines and method of winding and dyeing yarn, thread and the like and pertains particularly to the intermittent dyeing of lengths of yarn uniformly as to the application of the dye,

- as to the extent of the dyed lengths and as to the spaced distance of said dyed lengths.

It is customary for the manufacturer of knit fabrics to rewind yarn as it comes from the manufacturer of yarns on to tapered or conical bobbins and as the winding is effected by tension applied through the rotary bobbin, the speed at which the yarn passes any predetermined point varies continually during each cycle of operation in accordance with the varying circumferem-e of the bobbin. Therefore the intermittent application of dye to the traveling yarn effected by moving the yarn at regular predetermined intervals -into contact with a saturated wick in the manner described in Ainsworth Patent #1,274,972 produces an irregular and non-uniform result, the spaced distance between the dyed lengths and the extent of the dyed lengths varying in accordance with the varying speed of the traveling yarn.

- Further, the movement of the yarn across a stationary wick tends to dye one side of the yarn only and soon wears out the contacting portion of the wick.

An object of this invention is to produce a method and a machine by which the dye will be applied to the yarn in uniform lengths, uniformly spaced by wiping contact of the yarn with a dye carrying element' by a cross bar 8- description contained in connection with the accompanying drawings in which Figure 1 is an end elevation of a winding machine equipped with my invention.

tending platform '2 serving as a support for a plurality of spools 3'-. of yarn, thread or the like in the form as it comes from the manufacturer of yarns. The winding apparatus consists of spindles 3- mounted for rotation about vertical axes, each spindle adapted to carry a tapered or cone shape bobbin -4- upon which the yarn is adapted to be wound preliminary to its use in the usual knitting machine. The yarn in its passage from spool -3- to bobbin 4 passes over a rest --5- projecting from and carried by nut 6- threaded on to a vertically arranged screw threaded rod -7- carried supported by a series of vertical shafts -9 journaled in the framework and having their lower ends resting upon rollers 10 mounted upon the ends of levers llcarried by rock shafts --12 supported by the frame and extending from front to rear thereof. o

In Fig. 2, I haveillustrated but one of the shafts 9.- and its operating mechanism whereas the present commercial machine utilizes three such shafts for supporting each bar 8, but the construction of each shaft and the mechanism for elevating it is the same and will readily be understood from the disclosure of Fig. 2.

In the present commercial machine the shaft 12 is rocked or actuated by suitable mechanism driven from shaft 13- which shaft may in turn be driven from drive shaft -l4 through the medium of belt 15 a a The rocking movement given to shaft -12 will intermittently elevate shaft -9 and bar 8-, to thereby elevate rod --7, nut 6 and rest 5 carried thereby to properly move the yarn vertically of the cone shaped bobbin to cause the same to wind evenly and uniformly thereon. The mechanism so far described is old and well known. It will be understood that the winding mechanism at one side of the machine is duplicated at the opposite side and the description of one of such mechanisms serves to describe both. At each side of the'machine andcarried by the frame work thereof, is a tank 16- which may be formed to extend throughout the entire length of the machine and is provided with a dye applying element for each spindle 7. This tank may be of any suitable form and construction and as shown is formed of a metallic cylinder -17- having its ends closed by caps -18 which may be combined with nuts 19-- and packing 20 to insure a liquid tight joint. The cylinder -17- has arcuate portions of its wall removed preferably at spaced intervals conforming substantially to the spa'ced dis tance of spindles 7 said arcuate portions removed being equal in number to the spindles upon that side of the machine. The openings thus formed are substantially closed by plates -2l having flanges -22 at the front and rear thereof for securement to the cylinder 17, the surface of the plates lying substantially in a chord of the circumference of the cylinders The plate -21 is provided with a groove -23 in its upper exposed face and this groove preferably as shown extends from one end along one edge of theplate for a short distance, then diagonally across the plate to a point spaced from the opposite end thereof and then along the opposite edge to said opposite end, for a purpose hereinafter described. The plate is provided with a central opening 28' leading from the interior of the cylinder -17 into said groove 23 and may have substantially circular pins 2 1- rising in the groove to guide the yarn through the diagonal portion of said groove.

For the purpose of applying dye to the traveling yarn a rotary dye applying element 25 is provided pivotally carried by a shaft having its ends mounted respectively in flanges -26 and 27 preferably integral with and extending down-' wardly from plate -21. This element as shown is in the form of a circular wheel having its periphery projecting through the opening --28' in plate 21-. As shown the element is built up from a pair of op posite metallic plates 28-- confining between them an absorbent disk -29- of somewhat greater diameter than the plates. The plates and disk are mounted upon a sleeve -30- in turn mounted upon shaft ---3l-- having its end journaled in the flanges 26- and 27. The yarn guided by the eye '32 and guide 33- passes normally in contact with the periphery of the dye carrying applying element 25-.

The movement of the yarn across the element 25 diagonally of the plate 21 and at an angle other than a right angle with the axis of said element will cause the dye applying element in its rotary movement to give to the yarn a rollingmotion as it is wiped across the said element whereby the dye will be substantially uniformly applied to the entire circumference of the yarn.

The dye may be applied to element -25 in any suitable way and in the preferred manner illustrated is applied and the element rotated by a positively driven wheel --34 mounted-upon a countershaft '-35-, said wheel preferably embodying an absorbent or other disk '36- contacting with the disk 29 to frictionally drive the element 25-- as well as uniformly apply dye thereto. The countershaft ,35 may as shown be journaled in one end 8- of tank -16 and in bracket '37 carried by the cylinder 17.

The method and apparatus for driving shaft -35- at a speed varying'in accordance with the varying speed of the traveling yarn constitutes an important part of this invention and consists of a pulley 38, belt driven from pulley 39 formed in connection with and rotating with a cone shaped roller -4(), which cone shaped roller is adapted to be frictionally driven by a reversely arranged cone shaped roller l1- positively driven as from shaft 14-- by belt 42 The cone shaped roller 41-- is mounted on shaft ---42--' having its opposite ends journaled in a substantially U-shaped casting -43- formed with a pair of legs 44- adapted to rest upon bracket l5- carried by frame -1-, said casting secured to said. bracket as by bolts -44:= constituting a stationary mounting for said cone shaped roller. The oppositely disposed cone roller is mounted upon a. shaft 46-- having its ends ournaled in a U-shaped bar 47 pivotally carried by arms -48- projecting from casting -43-. The cone roller 40 is normally pressed toward the cone shaped roller -41 by springs -49 positioned between opposite ends of the bar -&7- and the adjacent portions of casting-43 and the casting may be provided with the seats -50 for receiving portions of the springs and bar -4:7- may be provided with an adjusting screw for properly tensioning thesprings. These springs bear against the bar "-47- below the pivots -'-51 thereby tending to rock the bar about such pivots and hold the roller -.-40-- in proper position.

For the purpose of effecting the variable drive required by this invention a loose belt 52- extends between the rollers 4'c0- and 41- and causes the one to frictionally drive the other at a speed dependent upon the position of the beltlongitudinally of the rollers. As illustrative, if the belt -52- lies. between. the rolls at a point where roller -40- is of largest diameter and roller 41 is of least diameter, roll 41 will drive roll -40'- at arelatively slow speed, whereas, if the belt 52- lies between the rollers at a point where the roll 4:1.' is of largest diameter, such roll will drive roll 40 at a relatively high speed and as the relative proportions of the cone shaped rollers vary in a manner similar to the variations in diameter of the cone shaped bobbin, the drive of roller 40 by roller 4l may be made to vary in accordance with the variation in speed of the traveling yarn as woundupon bobbins -.4- ifthe belt 52- can be made to vary its position between the cone rollers -40 and -41- in accordance with the'movement of guide 5- controlling the vertical position of the traveling'yarn relatively to the bob-- This is accomplished by. mounting belt 52- upon a roller ,53 carried from a clip -54: slidably mounted upon bar 55-, which bar is carried by the upper spaced ends of casting 4=3-. The clip 54.- is connected by bar -56- with a rock arm -57 carried by the rock shaft -12. By making the effective radius of rock arm 57 substantially the same-as the effective radius of lever --11 the move- I ment of clip 54- along shaft will conform with the movement of shaft 9 and guide -5- and the distance of movement will be the same so that the speed of of guide --33-.

roller 40- will vary in accordance with the speed of the traveling yarn.

The countershaft -35 and element 25 will therefore, be driven at a speed varying in accordance with the speed of the yarn.

In order to effect intermittent dyeing of the yarn in the use of this machine'it becomes necessary to move the yarn intermittently out of contact with the dye applying element and by utilizing countershaft -35 as a driving agency for this purpose the lifting or elevating means will act upon the yarn at varying'intervals dependent upon the speed of the traveling yarn to thereby effect dyeing in uniform lengths, uniformly spaced. For this purpose a substantially U-shaped plate 58- is pivotally connected to flange ---59 extending upwardly from plate -3lby bolt 60-, the arm -6lextending downwardly through plate 21- and carrying a screw -62-, upon which the upper slotted end of pawl -63- is mounted. The pawl -63- is pivoted on bolt 64 carried by the arm -26- and the pawl has its end 65 be disposed upon opposite sides of wheel 25- and a raised connecting portion -69 lying above and extending across the periphery of said wheel. Normally the base of the hooks lies sufliciently below the periphery of wheel -25-- to permit the thread when tensioned to move across and l in contact with the absorbent disk '29- In threading the yarn on the machine it may be passed through eye -32 and perspring pressed into engagement with a cor- 1.00 to form a pair of hooks "68 adapted to mitted to lie in contact with post 24-. I

without extending through'the diagonal portion of the channel, but rather resting upon the concave portion of the'upper surface When the proper connection has been made the operator merely pushes the yarn or thread across the guide 1 --33-until it passes down around the end ofsaid guide and is drawn into the lateral concavity 7.0 properly positioning the yarn in the groove 23 for effecting dyeing operation.

Although dye may be supplied to thetank -16- in any suitableway, I have shown a dye containing reservoir 71 suitably connected to pump 72 having its'piston 73. driven by eccentric attachment to pulley -38. The pump is provided with an inlet pipe -7 4%.and an outlet pipe the latter pipe communicating preferably with both tanks 16. -'('4 and -75-- adjacent the pump are provided with the usual opposed non-return valves 76 and -7T-. By this means the liquid is continuously drawn from reservoir 71 and supplied to the tanks. Any surplus in the tank -l6- is returned to the reservoir 71- through return pipe 78 Which has a fitting -79 extending upwardly through the wall of tank l 6 and opening at the top for telescopically receiving sleeve 80- having a stop shoulder -81-. The fitting 79- is provided with a slot -82' beginning at the internal surface of the lower wall of tank 16 and terminating some distance thereabove for registration with a-smaller slot '83 formed in the sleeve -80--, the slot .83 determining the size and position of the discharge opening from tank 16. Preferably sleeve '80- carries a screen -84 to. retain any lint, etc., mixed with the dye. When the sleeve -80 is withdrawn from fitting 79 all of the dye will flow from tank -16 to receptacle 71-. An additional overflow pipe -85 is provided in communication with pipe 78 which prevents filling of tank 16 beyond a predetermined point even though the communication through fitting 79--- and sleeve 80 becomes partially or wholly obstructed.

In the use of dye considerable ev-apora-' air of s rin ressed ri Jill" levers pivoted to the body of clamp 89 A connecting rod 91 is pivotally mounted upon clamp -89-xand has its opposite end pivotally secured to a pointer 92- in advance of the pivot -93- of said pointer. The pointer 92- is pivotally secured to the plate -94=-, which plate in turn contains suitable indicia or a suitable scale of measure showing the amount of'variation in the liquid contained 1n reservoir 71 as in pints, quarts or the like, or divisible parts thereof. By properly adjusting theclamp 89 as at night after the operation v of the machine has ceased sothat the pointer registers zero, the amount of the evaporati0n of the liquid dye in reservolr 71-.-

The pipes will be shown upon the dial --94-, by reason of the fact that the downward movement of sleeve --87 will cause a proportionate relative movement of pointer --92-- so that the. latter will indicate upon the dial the exact variation in the amount of liquid in reservoir 7l. Suflicient liquid as for instance, denatured alcohol may be added to reservoir 7 1- to bring the pointer back to zero thereby accounting for all evaporatlion and utilizing the entire capacity of the ye.

The operation of the machine will be readily understood from the above description, and although I have shown and described a specific construction of apparatus and parts thereof as illustrative of an embodiment of my invention, I do not desire 'to limit myself to the details of construction form or operation of the apparatus or its parts as many changes and. modifications in details and substitution of equivalents may be made without departing from the invention as set forth in the appended claims.
